The springs of the San Marcos River have plenty of extraordinary traits: Every day they release over 100 million gallons of water. They form the primary habitat for several endangered species, and one of the longest-inhabited places in North America. But the most magical thing about the springs is actually no longer there - its unique submersible theater, or 'Aquarena,' which once gave audiences a window into an underwater world of mermaids, clowns, and a swimming pig named Ralph.
Collectors Weekly spoke with some mermaids about their experiences at Aquarena Springs, who often performed for eight hours a day in any weather.
